I guess this is related to an OpenID issue (I previously logged in using Facebook, but as many customers disable it, I started to log in using Google).

Can you check please?

I am not sure if it's related, but in Stack Exchange I see I joined Meta Stack Overflow four months ago and have 208 reputation; today I "see" only 101.

[edit] I'm quite sure now my accounts are messed concerning the OpenID I used.
Is there any way to clean, reattach, merge, etc. all my accounts with my main OpenID provider (Google) and Facebook as the alternative OpenID provider?
